Introduction
Thank you for purchasing the HIOKI
"Model 3403,3404 TACHO HiTESTER".
To obtain maximum performance from
the instrument, please read this manual
first, and keep it handy for future
reference.
Inspection
When you receive the instrument,
inspect it carefully to ensure that no
damage occurred during shipping. If
damage is evident, or if it fails to operate
according to the specifications, contact
your dealer or Hioki representative.

Safety Notes
DANGE R
This instrument is designed to comply
with IEC 61010 Safety Standards, and has
been thoroughly tested for safety prior to
shipment. However, mishandling during
use could result in injury or death, as
well as damage to the instrument. Be
certain that you understand the
instructions and precautions in the
manual before use. We disclaim any
responsibility for accidents or injuries not
resulting directly from instrument
defects.
This manual contains information and
warnings essential for safe operation of
the instrument and for maintaining it in
safe operating condition. Before using it,
be sure to carefully read the following
safety precautions.

Overvoltage Categories
This instrument complies with CAT I
safety requirements.
To ensure safe operation of
measurement instruments, IEC 60664
establishes safety standards for various
electrical environments, categorized as
CAT I to CAT IV, and called overvoltage
categories. These are defined as follows.
____________________________________________

____________________________________________
CAT I: Secondary electrical circuits connected to
CAT II: Primary electrical circuits in equipment
CAT III: Primary electrical circuits of heavy
CAT IV: The circuit from the service drop to the

transformer or similar device.

power cord (portable tools, household
appliances, etc.)

outlets.
service entrance, and to the power meter
and primary overcurrent protection device
(distribution panel).
Higher-numbered categories correspond
to electrical environments with greater
momentary energy, so a measurement
device designed for CAT III environments
can endure greater momentary energy
than a device designed for CAT II. Using
a measurement instrument in an
environment designated with a highernumbered category than that for which
the instrument is rated could result in a
severe accident, and must be carefully
avoided.

Accuracy
We define measurement tolerances in
terms of f.s. (full scale), rdg. (reading)
and dgt. (digit) values, with the following
meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale
length. This is usually the name of the
currently selected range.
rdg. (reading or displayed value)
The value currently being measured and
indicated on the measuring instrument.
dgt. (resolution)
The smallest displayable unit on a digital
measuring instrument, i.e., the input value
that causes the digital display to show a
"1" as the leastsignificant digit.

Notes on Use
Follow these precautions to ensure safe
operation and to obtain the full benefits
of the various functions.
DANGE R
To avoid damage to the instruments and
potentially life-threatening hazards,
observe the following precautions:
Be careful when measuring with the
contact adapter because rotation and
vibration of the instrument can produce
erratic results with either high or lo w
rotation speeds. Hold the main body
firmly against the rotator. Do not place
the instrument on a tripod when making
measurements.
If the contact tip is not fully inserted over
the contact adapter shaft, it could fall off
the shaft by touching the rotator. Make
sure the contact tip is firmly inserted over
the adapter shaft before making
measurements.

WARNING
To avoid damage to the instruments and
potentially life-threatening hazards,
observe the following precautions:
Always use the screw to tighten the
contact adapter to the main body. If it
becomes loose, the instrument may
vibrate or be dislocated and become a
hazard.
When using the contact adapter for
measuring, the instrument is subject to
vibration, so measurements should be
made only below 20,000 r/min or 333 r/s.
Use either the specified Hioki 9035 AC
ADAPTER or another 300 mA/6 V adapter
with 5-mm diameter and negative center
contact that complies with IEC 60950
safety standards.
CAUTION
Do not store or use the instrument where it
could be exposed to direct sunlight, high
temperature or humidity, or condensation.
Under such conditions, the instrument may
be damaged and insulation may deteriorate
so that it no longer meets specifications.
To avoid electrical hazards and damage to
the instrument, do not apply voltage
exceeding the rated maximum to the output
terminals.
____________________________________________

____________________________________________
NOTE
Depending on the material of the object
to be measured or method of touching
the contact tip, the measurement error
may occur.
Do not perform measurements in
locations with high humidity or where
those are subject to intense ambient
light.
Avoid scratching or dirtying the two
lenses inside the detector window.
Do not switch between FAST and
SLOW modes when the instrument is
set to the MAX or MIN hold
measurement mode. (3404 only)

Overview
1.1 Product O verview
This instrument is a non-contact, highly
portable tachometer that functions by
measuring the visible light reflected from
reflective tape attached to the object to
be measured. It can also be used as a
contact type tachometer by attaching the
optional 9213 CONTACT ADAPTER,
sold separately.
